Evaluate the mesh current $i_1$ in the given circuit: 
To evaluate the mesh current \(i_1\) in the given circuit, we will apply Kirchhoff's Voltage Law (KVL) to each mesh. The circuit consists of two meshes, and we will define the mesh currents as \(i_1\) for the left mesh and \(i_2\) for the right mesh.
Mesh 1 (Left Mesh):
Mesh 2 (Right Mesh):
Solve the Equations:
Rearrange Equation 2: \(2i_1 = 7i_2 - 1 \Rightarrow i_1 = \frac{7i_2 - 1}{2}\)
Conclusion:
The correct option is \(i_1 = 1.132 \, A\).
